i know it’s an old thread, but if it’ll help someone, then Tobii.EyeX.Configuration.exe has some command line features:
c:\Program Files (x86)\Tobii\Tobii EyeX Config>Usage: Tobii.EyeX.Configuration.exe [optional arguments]
Optional arguments:
-R, –resolve Resolve configuration
-N, –new-profile Create new profile and calibrate
-C, –calibrate Calibrate the current profile
-S, –setup-display Setup display configuration
-P, –eye-position Eye position
-G, –guest-calibration Calibrate for the guest account
-H [-samples <numSamples>] [-sampletime <seconds>] [-timeout <seconds>] Hardware test, default values are (if argument is missing): required samples 60, sampleTime 3 seconds and timeout 7 seconds
-h, –help This text
it helped me to invoke re-calibration from command-line
also, if the tray icon is active, you can use the CTRL+SHIFT+F10 keyboard shortcut to activate calibration of guest profile
